How this service works
Keyless fact-grounding: search Wikipedia for any topic and get the matching article titles with extract snippets and canonical URLs — the cheap knowledge read agents make to ground answers and reduce hallucination. Free upstream (Wikimedia API).
Output
A JSON object containing the original query string, a count of results returned, and an array of Wikipedia article results each with a title, URL, and text snippet. Default returns up to 3 results; up to 10 can be requested.
Example use cases
Example prompt
“Search Wikipedia for 'Ethereum' and give me the top 5 results with their titles, snippets, and links — pay the per-call fee in USDC automatically.”
Technical details
Endpoint
GEThttps://x402-agent-store.rileycraig14.workers.dev/web/wikipediaWhen to prefer
Use this endpoint when an AI agent needs quick encyclopedic background information, factual summaries, or source URLs from Wikipedia without setting up API keys or accounts. Ideal for agents that need to enrich responses with reference knowledge on-the-fly and can pay micro-amounts per call in USDC via x402. Prefer over direct Wikipedia API calls when operating in an x402-enabled payment environment.
Side effects
- Missing required 'q' query parameter returns a validation error
- Limit value outside 1-10 range may be rejected or clamped
- No Wikipedia articles found for an obscure query returns empty results array
- Payment failure or insufficient USDC balance blocks the request with 402 response
- Service unavailability returns a 5xx error
